Dwarf Rhode problem
Its easier if I show you a few pics of our Dwarf Rhode.
This year it has been very poor, in fact very ill, more like it. Does anyone know the cause of this ailment. Pics are 800 x 600 so take a little time to load... http://www.daj.fseltd.btinternet.co.uk/rhodiproblem.htm thanks Don |

Jenny Jenny, thanks for reply To much sun.......we are in the UK :-) The plant has stood in the same area for 5 years now and this is the first poor show. The pot is 12" diameter and 12" inches deep. Do you think this is to small for 5+ year plant. We thought as a dwarf it should be restrained by the pot. thanks Don |

Do you think this is to small for 5+ year plant. We thought as a dwarf it should be restrained by the pot. thanks Don Hi Don, Jenny's probably quite right on both counts. Knock your Rhodi out of its pot and see if it's pot bound. If the roots are completely filling the pot, two things will be happening: 1. The soil ball will dry out very rapidly and will be difficult to keep wetted. 2. The roots will be touching the sides of the pot and getting very hot with the sun on it. Your Rhodi prefers a moist, cool root run. It is currently getting neither of those. Although you say it coped with sunny conditions until now, it probably coped with them because it was not so stressed. I think that if you repot your Rhodi in ericaceous compost (which will also have the effect of feeding it), water it in well and stand it in a shadier place, you will see it recover. The food supply in the compost will only last 4-6 weeks, so be prepared to feed again in a couple of months' time. It will also help your plant if you deadhead it, so that it's not trying to make seed. This is standard advice for Rhodies, but is especially important while your plant is recovering.

'Dwarf' is a relative term in rhododendrons; some can go to 6ft, but 'Bow Bells' is smaller than that, 3 - 4 ft IIRC. I'd go with JennyC on the possible need for re-potting. Carefully knock it out of it's pot and if the root-ball is a solid mass of roots, consider re-potting in John Innes ericaceous compost. Phosphorus deficiency causes reddish-purple blotches. The later stages of nitrogen deficiency can produce reddish blotches on tips and outside edges of leaves (but usually after they have gone rather yellow-green). When did you last feed it? Use a feed suitable for ericaceous plants, applied monthly. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

Do you think this is to small for 5+ year plant. We thought as a dwarf it should be restrained by the pot. thanks Don Looks like 'Bow Bells' or similar williamsianum hybrid. R. williamsianum itself has bronzy young foliage, and this can be inherited by it's offspring, Bow Bells being no exception. But this wouldn't explain why it wasn't showing this colour in previous years. Also, the rather blotchy appearance suggests a disorder of some sort. Phosphorus deficiency causes reddish-purple blotches. The later stages of nitrogen deficiency can produce reddish blotches on tips and outside edges of leaves, but usually after they have gone through a rather yellow-green stage. When did you last feed it? You should use a high-nitrogen feed suitable for ericaceous plants, applied monthly after flowering until the end of June, and then a high potash feed in July to encourage flower bud formation for next year. 'Dwarf' is a relative term in rhododendrons; some 'dwarves' can go to 6ft, but 'Bow Bells' is smaller than that, 3 - 4 ft IIRC. I'd go with JennyC on the possible need for re-potting. Carefully knock it out of it's pot and if the root-ball is a solid mass of roots, consider re-potting in a tub in John Innes ericaceous compost. Don't forget to scrape the outer surface of the root ball to disturb the roots, otherwise they'll never grow out into the fresh compost. -- Chris E-mail: christopher[dot]hogg[at]virgin[dot]net |

Don well we removed the Rhode from its pot and there was no sign of root balling or even touching the pot and the loam was in great not tight or loose condition. anyways we have now repotted in ericaceous loam and removed the now dying leaves and flower heads and placed it into a cooler spot for the rest of this year. Fingers crossed for next year now. Still our other dwarf seems to be thriving. thanks Don |
